THE ALFVEN RESONANCE IN A MAGNETIZED DUSTY PLASMA

Wave propagation in a dusty magnetized plasma at frequencies below and of the order of the ion-cyclotron frequency, and with a non-zero elec tron temperature is considered. The general dispersion relation for wa ves propagating at an arbitrary angle with respect to the external mag netic held and for finite ion-cyclotron frequency is derived and discu ssed. Modification of the Alfven resonance absorption mechanism due to the presence of a finite proportion of the negative charge of the pla sma on stationary dust grains is investigated.
